  • Using (and reviewing) non-UK structures to hold personal wealth. 
  • Advising on UK succession laws and how conflicts with non-UK succession laws can be resolved.
  • Assisting with UK inheritance tax planning and the implementation work which flows from this.
  • Assisting with the preparation of a wide range of documents, including wills, powers of attorney and supplementary trust documents.
  • The administration of estates, often involving a cross-border element and/ or other complexities. 

A word from one of Louise’s clients: 

"My family and I had the very good fortune of being introduced to Gateley Legal a few years ago. We have since relied on Gateley's outstanding professionals for their immensely valuable legal advice and assistance, and we continue to do so without hesitation and with full confidence.

It has been a pleasure to work with Louise O'Toole in particular. Louise has personally, patiently and compassionately guided us through our most challenging times, with utmost professionalism and dedication. She is a very thorough and competent professional who has always and without exception instilled in us the highest confidence that we are in very good hands and that our best interest is at the forefront of all she has undertaken on our behalf. Her ability to simplify the most complex of matters for our benefit has also always been greatly appreciated.

We have accomplished a great deal with her kind support and remarkable diligence, and for that we are eternally grateful."
